Specification of Letters Patent.

Patented Mar. 6, 1917.

Application filed February 7, 191e. Serial No. 76,551.

To all 'whom t may concern:

Be it known that l, JAMES l. FOUGH, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and tirate of California, have invented certain new and useful improvements in Tractor Yilevices', of which the following is a specication.

This invention relates to improvements in traction devices and has particular relation to mechanism for converting vehicles of various types into vehicles having greater traction power, and especially-into vehicles adapted to operate as tractors, such as are commonly employed in various agricultural pursuits. f

lt is an object of the invention to provide a traction mechanism which may be readily applied to any ordinary vehicle, and especially to a vehicle designed for road travel, whereby the vehicle is adapted for use on loose, uneven` surfaces or ground or on cultivated ground, the vehicle practically becoming a tractor.

It is also an object of the invention to provide a tractor attachment which may be secured upon the running gear of a road vehicle, broad tractor wheels being substituted for the usual road drive wheels of the vehiole.

lVith these and other objects in View the invention comprises certain novel constructions, combinations and arrangements o parts as will be hereinafter more fully described and claimed.

ln the accompanying drawing forming a 'part of thisspeciication:

Figure 1 is a view partially in section and partially in top plan of Nehiele, the parts being broken away to show the arrangement 'when the vehicle is converted into a tractor, embodying the features of the present invention. y

Fig. 2' is a vertical section view taken upon the line 2-2 of Fig. 1.

Fig. 3 is a detail sectional view taken upon the line 3-3 of Fig. EL Fig. a is a fragmentary view showing a portion of the chassis and the running gear of a vehicle with the tractor mechanism of thisinvention applied to the said chassis as well as'to the casing of the drive axle.

Fig. 5 is a transverse sectional view taken upon the line 5-5 of Fig. 4.

Fig. 6 is a detail fragmentary sectional view ofthe cross bar connection interposed between the tractor mechanism and the chassis of the form of device shown in Fig. 1l.

The traction or tractor mechanism of this invention is designed to make it possible to possible to draw or move cultivating implements and mechanisms over the ground. Practical embodiments of the invention have been illustrated in the accompanying drawing and the details and features of the invention will now be set forth, reference being had thereto. ln the said drawing, 6 in,- dicates the body portion of a passenger vehicle, 7 the chassis or main frame, S the casing of the rear or driving axle, and 9 the casing of the drive shaft communicating motion from the engine to the drive shaft. All these parts may be of any usual or ordinary type, and may be used to represent the parts of llight road vehicles or heavier passenger carrying vehicles orv the like. vThe mechanism of the present `invention is adapted for easy connection and attachment to the parts mentioned, without the necessity of any change therein, other than the re-` moval of the drive wheels which are commonly employed in road travel.

' The tractor attachment preferably comprises traction wheels 10 generally made with a broad ground engaging traction tread, which may be roughened if desired as indicated at 11. These traction wheels are mounted upon a suitable frame preferably having an axle 1Q and a yoke or attaching portion 13, the aXle is provided at its ends with journals 111 adapted to engage journal bearings 15 formed in the hubs of the wheels 10. Nuts 16 or other holding means are employed for movably retaining the wheels in l place on the aXle 12. The yoke or frame 18 is preferably rigidly secured to. the axle 12, as by means of clips 17, applied tothe out turned end portions 18 formed upon said yoke. The yoke 13 is usually of an angular shape and is adapted to be clamped to the axle casing 8 in any suitable manner for quick attachment or removal. Thus arched clamping bars or plates 19 may loe 'applied around the said casing 8 and securely fas- 110 ice remesa treads, whereby the vehielewill be adaptable for use on soft or broken ground.

2. A tractor attachment for motor vehicles comprising a frame adapted to be clamped uponthe drive axlecasing of the vehicle and adjustably engaging the casing of the transmission drive shaft, pinions adapted to take the place of the vehicle drive Wheels, and to be driven by the drive aXle of the vehicle, and gears upon the tractorvvheels for receiving motion from said pinions.

:8. A tractor attachment for motor vehicles comprising a yoke frame having means for adjustably securing it to the casing of a vehicle drive axle, and having means for bracing it with respectto the casing o the vehicle drive shaft, a draft beam held by said yoke, tractor Wheels carried by said yoke frame having vdrive gears thereon and pinions adapted to mesh with said drive y a tractor. a:

vehicle', a transverse axle, an adjustable clevis member mounted upon said transverse axle for connecting mechanism and attachf ments to the tractor attachment and tractor,

`Wheels mounted upon said transverse agile',

said tractor' wheels supporting said yoke and the drive mechanisin'of the vehicle, wherebyy the vehicle may/be converted into In testnnony'whereof, I have `hereunto set my handgiin presence of two Witnesses. JAMES R. FOUCH. lgVitnesses:
